III. FEATURE DISCUSSION 13New, Highly-Legible2.5-inch TFT LCDColor ScreenNew Display-off sensorin lenses such as the EF 400mm f/2.8L IS USM or the EF 600mm f/4L IS USM. All overthe world, photographers depend on Canon IS to help them achieve the highest possi-ble image quality.At some point, in-body stabilization may improve to the point at which such technologymay be appropriate for certain segments of Canon’s DSLR range. It would be senselessto rule out such a possibility. Even now, differences in unit cost are not enough to besignificant factors in such a decision. The bottom line is performance.A 2.5-in., 230,000-pixel, color TFT LCDscreen with a wide, 160° viewing angle isa welcome new feature of the Digital RebelXTi. Compared to the Digital Rebel XT's1.8-in. LCD screen, the display area isabout twice as large. Also, to improve themenu's readability, the font size has beengreatly increased. The LCD screen illumination is provided by three LED backlight mod-ules and the brightness adjustment range has been expanded by one level at both theminimum and maximum levels to a total of 7 steps. During brightness adjustment, ahandy and elegant grey scale is displayed along with the image.Thanks to a highly transparent LCD screen and a brilliant LED module, screen brightnessis about 40% higher than the maximum brightness of the screens found on the EOS-1DMark II N, EOS 5D, and 30D. This makes it easier to review images even in bright outdoorconditions. At the darkest setting, the display is not uncom-fortably bright, even in a dark place. The maximum bright-ness setting changes the gamma characteristic of thedisplay to increase the midtones, making theimage look somewhat overexposed, and high-light detail tends to be lost. Therefore, it isimportant that when checking an image'sexposure and colors, the brightness level beset to one of the middle five levels. Becausethe Digital Rebel XTi displays the camera set-tings at all times, users are recommended to setthe screen brightness to a suitable level whichwould not be too bright in the dark.When you put your eye on the eyepiece, a new display-off sensor (located below theeyepiece) senses your face and turns off the LCD screen automatically. This is to savebattery power and prevent the screen's brightness from disturbing your eye while look-ing through the viewfinder. The display-off sensor consists of an IRED emitter and light-receiving sensor. When the IRED light reflecting off the face is detected by the light-receiving sensor, the LCD screen turns off automatically.
